Worked Solution & Example Answer:Using Figure 9a and Figure 9b, analyse the data shown - AQA - A-Level Geography - Question 5 - 2019 - Paper 1
Step 1
Analysis of geographical issue or question
Answer
The Kilauea Volcano has been experiencing significant volcanic activity, particularly along the East Rift Zone. The data from Figure 9a indicates areas of lava flow and expansion, which appear to be moving primarily to the south and east. This elemental shift highlights the risk to local human settlements, particularly around Leilani Estates, where the lava flows come dangerously close.
Step 2
Clear interpretation of quantitative evidence
Answer
In Figure 9a, the flow expansion range from May 24 shows the active lava zones are spreading at rates of approximately 5-15 meters per hour. This emphasizes the rapid nature of the eruption, posing potential hazards to communities such as Pāhoa and Leilani Estates, which lie within direct proximity of the lava flow paths.
Step 3
Connection between different aspects of the data
Answer
Figure 9b complements the information from Figure 9a by providing a visual representation of the eruption. The satellite image highlights the expansive coverage of the lava flow towards the ocean, visible in red hues, and shows the plume of ejected volcanic material. The plume height, measured from two to three kilometers, demonstrates the intensity and vertical reach of the volcanic activity, connecting with the flow details presented in Figure 9a.
